For the most part, Colorado waterfalls are fairly accessible and easy to find, often being located in plain sight (with or without hiking). However, there is one Colorado waterfall that is so hidden and virtually unknown that most people will never get the privilege of seeing it. That waterfall is, of course, Rainbow Falls.
Located under a highway overpass near Manitou Springs, Rainbow Falls is a beautiful stream of water that is surrounded by rocky cliffs and fed by the nearby Fountain Creek.
Nicknamed the "Graffiti Waterfall" (for obvious reasons), Rainbow Falls sits beneath its namesake 1934 bridge, which is listed on the National Register of Historic Places, yet it was still often overlooked and virtually forgotten for several decades.
After the summer flooding of 2013, Rainbow Falls was again on locals' radar, leading to the formation of the Rainbow Falls Recreation Area and the restoration of both the Rainbow Falls Bridge and graffiti-laden waterfall.
Since the clean-up is still in progress, it is recommended to verify that the area is open before visiting, which can be done by visiting El Paso County's website.
The Rainbow Falls Recreation Area Trailhead can be accessed by taking I-25 to Exit 24 (Cimarron), heading west for 5.5 miles, and turning left onto Serpentine Drive.
